Coinbase: Seamless MongoDB to PostgreSQL Migration
- chews 6y agoCoinbase ran mongodb for financial math .
- erentz 6y agoA strange choice that possibly explains so many of the stories of peoples lost balances over the years. Even recently (in the past two weeks) Coinbase is still having periodic outages where they cannot process orders and where orders get executed silently and fail to show up in the balances and failures to be able to withdraw funds. While of course their status page shows no outages (or in this recent one blames Amazon connectivity for your orders executing in the background and withdrawal page spewing errors). Several years on you’d think they’d have fixed this.

- redis_mlc 6y agoCoinbase is against hiring DBAs, so have experienced several large outages and likely hundreds of micro-outages in the past couple of years, mostly from simple things like missing indexes. They did a public talk on this in 2019, but get upset when it's mentioned. A lot of SV unicorns are solely focused on features, and do not take eng. operations seriously even after signing up large numbers of paying clients. They all get religion after a major data loss, or their head of sales loses it after a major client cancels. Source: DBA who attended one of their post-mortem lectures.
